android xutils怎么用session

Answer 1

之前使用过XUtils框架做过项目，当时因为session纠结了好久，但是解决了，现在回想起来，好像没有备份，赶紧写份笔记备份下，以后方便使用。
主要是登陆服务器后，应该保存一个登陆状态，登陆后，会保存个登陆状态，只有保存这个状才能有权限访问对应的内容，否则，返回的是一堆html格式的网页。
这时候，就会考虑到保存Cookie。直接上代码吧：
这里是登陆界面：
java">
MainActivity.java对应的import

import org.apache.http.client.CookieStore;
import org.apache.http.cookie.Cookie;
import org.apache.http.impl.client.DefaultHttpClient;
MainActivity.java
1 private void httpLogin() {
2 final HttpUtils http = new HttpUtils();
3 RequestParams params = new RequestParams();
4 String url = "http://192.168.1.60/auto/login_Login.action?oper.operatorName=123&oper.password=123";
5 final String urlPost="http://192.168.1.60/auto/login_Login.action";
6 params.addBodyParameter("oper.operatorName","123");
7 params.addBodyParameter("oper.password","123");
8 http.send(HttpRequest.HttpMethod.POST,
9 urlPost,
10 params,
11 new RequestCallBack<String>() {
12
13 @Override
14 public void onStart() {
15 pg.show();
16 Log.d("jack",urlPost);
17 }
18
19 @Override
20 public void onLoading(long total, long current, boolean isUploading) {
21 pg.show();
22 }
23
24 @Override
25 public void onSuccess(ResponseInfo<String> responseInfo) {
26 pg.dismiss();
27 Log.d("jack",responseInfo.result);
28 //===========================
29 // 取得sessionid.........................
30
31 DefaultHttpClient dh = (DefaultHttpClient) http.getHttpClient();
32 MyCookieStore.cookieStore = dh.getCookieStore();
33 CookieStore cs = dh.getCookieStore();
34 List<Cookie> cookies = cs.getCookies();
35 String aa = null;
36 for (int i = 0; i < cookies.size(); i++) {
37 if ("JSESSIONID".equals(cookies.get(i).getName())) {
38 aa = cookies.get(i).getValue();
39 break;
40 }
41 }
42 Log.d("jack", "比较sessionid" + aa);
43 //===========================
44 Intent intent = new Intent(MainActivity.this,SecondActivity.class);
45 startActivity(intent);
46 }
47
48 @Override
49 public void onFailure(HttpException error, String msg) {
50 pg.dismiss();
51 Log.d("jack","哈哈"+msg);
52 }
53 });
54 }

关键代码：
1 //===========================
2 // 取得sessionid.........................
3 DefaultHttpClient dh = (DefaultHttpClient) http.getHttpClient();
4 MyCookieStore.cookieStore = dh.getCookieStore();
5 CookieStore cs = dh.getCookieStore();
6 List<Cookie> cookies = cs.getCookies();
7 String aa = null;
8 for (int i = 0; i < cookies.size(); i++) {
9 if ("JSESSIONID".equals(cookies.get(i).getName())) {
10 aa = cookies.get(i).getValue();
11 break;
12 }
13 }
14 Log.d("jack", "比较sessionid" + aa);
15 //===========================

这里面的MyCookieStore是自定义的一个保存类：
MyCookieStore.java
1 import org.apache.http.client.CookieStore;
2
3 public class MyCookieStore {
4
5 public static CookieStore cookieStore=null;
6
7 }

最后就是在登陆后访问服务器的时候添加一句话：
http.configCookieStore(MyCookieStore.cookieStore);

给个类里的代码看看吧：
SecondActivity.java
1 private void httpLogin() {
2 HttpUtils http = new HttpUtils();
3 final String urlGet="http://192.168.1.60/auto/carModel_queryPL.action";
4 http.configCookieStore(MyCookieStore.cookieStore);
5 http.send(HttpRequest.HttpMethod.POST,
6 urlGet,
7 new RequestCallBack<String>() {
8
9 @Override
10 public void onStart() {
11 pg.show();
12 Log.d("jack",urlGet);
13 }
14
15 @Override
16 public void onLoading(long total, long current, boolean isUploading) {
17 pg.show();
18 }
19
20 @Override
21 public void onSuccess(ResponseInfo<String> responseInfo) {
22 pg.dismiss();
23 Log.d("jack","排量"+responseInfo.result);
24 }
25
26 @Override
27 public void onFailure(HttpException error, String msg) {
28 pg.dismiss();
29 Log.d("jack","排量"+msg);
30 }
31 });
32 }
